Chris Martin to guest star in 'The Simpsons'

Coldplay frontman Chris Martin has become the latest celebrity to secure a guest appearance in The Simpsons, according to Entertainment Weekly.

The 'Viva La Vida' star will cameo as himself after Homer Simpson wins a million dollars in the lottery and hires Martin to perform a private concert for himself and son Bart.

Executive producer Al Jean teased that the episode will see Martin having to stop singing every time Bart went to the bathroom.

Other stars who have been lined up for the animated program's 21st season include comedian Sarah Silverman, who will play Bart's new girlfriend, and Anne Hathaway, who will voice a princess character that is introduced to Krusty The Clown's show.

Seth Rogen, Jonah Hill, Neve Campbell and Eartha Kitt, who recorded a segment before her death last year, will also appear.
